Furthermore, since an alkoxysilane group capable of coupling with glass is introduced into the acrylic main chain, adhesion with glass is improved. Furthermore, since it reacts with a small amount of moisture in the air and crosslinks through a condensation reaction, it can be cured at a relatively low temperature. Because it forms stable siloxane bonds between molecules, it has excellent heat resistance and temperature resistance.
